And to get rid of the 3 we justMoreAnd just subtract 4 from both sides. Giving us y minus 4 equals 3x. And to get rid of the 3 we just divide both sides by 3. But importantly it's the whole of the y minus 4 that we're dividing by 3.

So I get Y minus B divided by x equals 2 M X divided by X or we can write M equals.

What is rearranging equations? Rearranging equations changes the form of the equation to display it in a different way. This is sometimes called changing the subject.

Lesson Summary. Let's review. Solving by rearranging means you are moving the terms in an equation around to find your answer. When solving by rearranging, remember these rules: Use the opposite operation to move terms from one side to the other.
